When running PI COnnector opc ua this is automated created tags to the 2nd VM. Then all tags are updating.

Then I do setup this for the corporate network I used the 3rd VM PI to PI Interface connecting to the 4th VM Corporate Destination PI Server. I added all the tags that was created by the PI connector OPC UA from the 2nd vm Source PI Server,to the 4th VM Corporate PI Server.

Upon checking Some Tags are updating but some tags are values are I/O Timeoutto the Corporate destination PI Server.

Troubleshoot:

1. I again recreate the tags in corporate that have I/O Timeout.

2. Configurations of the tags in coporate are same with the source PI Server.

I/O Timeout is written when PI to PI is having connection issues to the source PI Data Archive. Please check the log files in the PI to PI interface node and check whether you can see any errors regarding connection issue. Also is the data going through buffer subsystem?

Actually this is on the Prod server already so this PI to PI connection have alot of connection to its Destination PI Data Archive. Do you have any ideas on how to check the log file in a specific tags only?

To get tag based log message, you can increase the debug level to maximum/log all tag writes in PI ICU for PI to PI interface.This will help in pin pointing where exactly the problem lies. If you have buffering enabled please check whether the buffer subsystem at PI to PI interface node is reporting any errors ?
